Step 01: Get Access Key

First step is to get an Access Key from Web3Forms. Create Access Key
Once you submit the form, you will get the Access key in your Email. Copy that key so that we can use this later.

Step 2: Create HTML Form

Create a form in your website with our form endpoint inside action attribute. Following is a simple example on how it should look like:

<textarea name="message" required></textarea>
<input type="hidden" name="redirect" value="https://web3forms.com/success">
<button type="submit">Submit Form</button>
</form>
<form action="https://api.web3forms.com/submit" method="POST">
<!-- REQUIRED: Your Access key here. Don't worry this can be public -->
<!-- Create your Access key here: https://web3forms.com/ -->
<!-- <input type="hidden" name="apikey" value="YOUR_ACCESS_KEY_HERE"> -->
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE">

<input type="hidden" name="replyto" value="[email protected]">
<!-- Required: if submitting without Javascript
(because by default web3form outputs json) -->
<!-- If javascript, use "window.location.hash" for redirects -->
<input type="hidden" name="redirect" value="https://web3forms.com/success">
<!-- Optional: But Recommended: To Prevent SPAM Submission.

<input type="checkbox" name="botcheck" id="" style="display: none;">
